1. Automatically shift the door wind?
There is no place where air filtration equipment is needed more than in health facilities. The concentration of airborne infectious pollutants will increase with the increase of population density. This worry is not limited to. Sanitariums and dentists also need air filtration. At present, energy-saving air filtration system is preferred.
1. Air shower time setting: This is the external time parameter option. Before or after the start or end of the air shower, the time delay can be changed by continuously pressing the up and down adjustment keys for 3 seconds. The adjustment range is 1-99 seconds, and is displayed by the double digit digital tube. After 5 seconds of adjustment, the system will automatically save the parameter value.
The management system should effectively prevent any possible biological, chemical and physical hazards through the analysis and control of the whole process from raw material production, procurement, processing to finished product manufacturing, distribution and consumption. It is necessary to control the temperature and humidity, and remove the organic pollutants accumulated in the air conditioning system, because once the switch is blocked, it will become a hotbed for the cultivation of microorganisms. Our company provides a wide range of air filtration systems to the global food and beverage industry to help control microbial contamination. (for details, please visit: Mengniu Group, Kangshifu group, Wahaha Group, COFCO group, Guitang group, Nongfu Shanquan, beer, etc.
The air shower channel is a personal purification device used by operators when entering the clean room. It uses high-speed clean air to blow and drench away the dirt from the people entering the room. The nozzle can be adjusted to effectively remove dust from the body and prevent external pollution from entering the clean area. It can also be used for large goods.
As long as public health is seriously threatened, the State Food Hygiene Department may require the relevant responsible departments to strengthen the implementation of necessary health and safety policies and measures. These measures may include recall and destruction of food, or even temporary closure of all or part of food processing plants with potential safety hazards. In order to ensure food safety, food manufacturers are required to confirm all aspects that may affect food safety, formulate appropriate safety management system according to ADPCM / HACCP (critical control point for hazard analysis), and ensure implementation, persistence and continuous improvement.
1。 Leakage detection of high-efficiency filter. After the installation of high-efficiency filter, the leakage detection shall be carried out according to the site leakage detection method provided in the code for construction and acceptance of clean room.
After the production or installation of the air shower room, the manufacturer or the owner of the air shower room shall carry out basic inspection to determine whether the air shower room is qualified and whether it can be put into use. The following several important testing standards sorted out by Jinyi purification air shower factory can be used for reference.
4. Purification air conditioning system scheme of centralized air supply: (1) centralized treatment of fresh air and decentralized treatment of fresh air; (2) single fan system and double fan system; (3) fan parallel system and fan series system. After the design of clean air conditioning system, the operation and management of clean air conditioning also has corresponding requirements, as follows: 1. The requirements of maintenance and management of purification air conditioning system, and the purified air of clean room should be monitored according to regulations.
2. Manual door the air shower room usually has a single door. When the induction zone receives the command, the door in one direction can be opened manually.
The traditional ventilation mode is that the whole ceiling of the workshop is covered with high-efficiency filters, and the whole ground is the return air grid plate. Now, the FFU produced by our company uses the filter device with its own fan, which solves the complicated installation and cost-effective problems. It is a quiet and good price unit in the market at present, which can transport high-quality circulating air for the clean room. Solution to the problem caused by the source of pollutants solution dust and air cause IC open circuit, short circuit, affect the yield of chemical filter module + ordinary, high efficiency filter / ffunh3, NMP external gas "T-top" phenomenon chemical filter module.
The air shower room is the necessary passage for people / goods to enter and leave the clean room, and it also plays the role of airlock in airtight clean room. In order to reduce a large number of dust particles caused by the entry and exit of people / goods, the clean air flow filtered by the high-efficiency filter is sprayed onto the people / goods from all directions by the rotary nozzle, so as to effectively and quickly remove the dust particles. The cleaned dust particles are then filtered by the primary and high-efficiency filters and then recycled to the air shower area.
(1) adopt the clean principle of international standard and the cabinet design. It adopts automatic control operation, double door electronic interlock, infrared induction automatic shower, and double door locking.
Press the emergency stop key for 2 seconds to enter the parameter setting state. At this time, the nixie tube displays SJ, the emergency stop key is used as the setting key, the air shower key is used as the page turning key, and the up and down adjustment keys can adjust the setting parameters. If you press the air shower key, the nixie tube will cycle display Ti, to, TC, Tl, TD, TN 6 parameters in turn. Corresponding to different parameters, press the up and down adjustment key to display the delay time or function status corresponding to the parameter. The system has 4 internal time and 2 function parameter settings: Ti external door unlocking delay setting, single air shower room to inner door unlocking delay setting, TC air shower time delay setting, TL lighting delay setting, TD function setting, TN door exchange setting. After setting, if there is no operation, the system will automatically store and exit the setting state within 5 seconds.
(5) after passing through the primary filter, the air is pressed into the static pressure box by the external rotor fan, and then filtered by the high-efficiency filter, the high-speed clean air flow is blown from the air outlet surface, and the clean air flow is sprayed onto the person with high-speed and uniform wind speed, which can effectively and quickly remove the dust particles attached to clothes / goods.
(3) door, door frame, air shower chamber made of all stainless steel, single and single air shower handle, thickened floor plate and air shower nozzle are the basic configuration.
In order to achieve the effect of blowing shower, the wind speed at the nozzle outlet of the air / cargo shower room can reach more than 25m / s, and the wind speed blowing to the person is * * 18m / s. The initial air shower time for the specification of double air shower room is set as 15 seconds.
